According to Reddit, many people -- both male and female -- have been cheated on in a similar way.

"My ex-husband cheated on me at his bachelor party the night before our (moderately expensive) wedding," wrote one user. "I didn't know it at the time, but he called me after, completely drunk on tequila, saying he wasn't sure he wanted to get married, realized he wanted to have more fun and freedom, etc. etc…"

Another man recalled the time an ex wanted to have a fling with him during her bachelorette party.

"She's been happily married since (according to fb)," he said. "I'm kind of terrified to get married. The weird thing is that I don't really hang out with a bad crowd or anything. My buddy is a big name head chef and my ex did a lot of humanitarian and charity work, basically dedicated her life to helping the poor."
